Promising review: "Holy $!*% y'all! I saw the reviews for this product and decided that I needed to try this out- for "science". I ordered it, and when it came I charged it as instructed and went ahead and gave it a go. Now, to keep the experiment completely unbiased, I started from non aroused — nothing special happening physically or mentally or imaginatively. Just got comfortable and followed the instructions. And oh my damn! 0-100 REAL QUICK!! We are talking a single minute or less and I soaked my sheets! Now, that in itself has never happened to me before, let alone mere seconds from nothing to eruption! I was scared, amazed, flabbergasted; just completely SHOOK. So I pulled myself together, pulled off my sheets and got in the shower. I let a week or so go by before I tried again, thinking it was a one time thing, but I was plain wrong. Same deal, except this time I was prepared and laid a towel down. Bottom line - this little magical penguin has changed the game. It's worth every single cent. You will not regret purchasing this! Only suggestion I have is that you invest in a good mattress protector if you don't already have one. Also, I can't wait to try this out with my partner — I think it will really add a certain spice to an already amazing experience. Maybe I'll update my review once I've tried that. Just.buy.it. For real." —M.
